What regulations must be followed when laying the Yunnan waterproof membrane for tunnel waterproofing? What is the scope of the installation?
Release date:
2020-10-31
Throughout the years, how to determine Yunnan Lincang Waterproof Membrane The scope of paving has always been a critical issue in engineering—requiring not only precise calculations and strong analytical and operational skills, but also the ability to master the right approaches and methods.
1. Yunnan Lincang Waterproof Membrane The waterproof layer consists of plastic Yunnan Lincang waterproof sheets combined with a cushioning layer, and should be installed in a separate manner—first laying the cushioning layer, followed by the waterproof sheets. Yunnan Lincang Waterproof Membrane ， Yunnan Lincang Waterproof Membrane Thickness not less than 1.5 mm;
2. Yunnan Lincang Waterproof Membrane It should be laid across the tunnel arch and sidewall areas, forming a waterproofing layer that works in conjunction with the post-lining drainage system. For tunnel sections with particularly stringent environmental requirements and strict drainage constraints, the waterproof membrane in Lincang, Yunnan, should ideally be installed in a fully enclosed configuration.
3. Yunnan Lincang Waterproof Membrane The installation should be carried out after the initial support structure has stabilized sufficiently and passed inspection. During installation, the substrate must be smooth and free of sharp objects, with a flatness requirement of D/L ≤ 1/6, where D represents the depth of the indentation between two adjacent convex areas on the initial support substrate, and L is the distance between these same two convex areas.
4. Yunnan Lincang Waterproof Membrane The waterproof layer should be securely anchored to the substrate, with anchor point spacing determined based on the substrate's surface condition. Specifically, spacing should be 0.5–0.8 m for the arch section, 0.8–1.0 m for the sidewalls, and 1.0–1.5 m for the tunnel floor. In areas with significant local irregularities, anchor points should be placed more densely in the concave regions.
